Scaling up quantum computers from dozens of qubits to millions is one of the most complex challenges across our industry. We’ve just published a paper that can have a huge impact on how quickly and efficiently we scale towards industrial relevance, via something called “safe lattice surgery” on high-rate codes. Read the scientific paper by here: https://lnkd.in/eZUBTm7d To run something like Shor’s famous algorithm, scientists have estimated that one would need thousands of “logical” (error corrected) qubits, which are each made from multiple physical qubits. There are almost infinite ways to construct logical qubits out of physical qubits, but some approaches have huge implications for how quickly #quantum computers can scale up. For example, one approach might take 20 physical qubits to build one logical qubit, while another might take only 5 physical qubits per logical qubit. When your scheme takes fewer physical qubits per logical qubit, scientists call it a “high-rate code”, and it is these “codes” that we are interested in developing. Of course, there’s no free lunch - we typically need extra qubits to do computation, which add an additional overhead in terms of physical qubit number. Once you have logical qubits, to perform “universal” computation, you also need things called “magic state distillation” and “lattice surgery” (there are other options, but for this post we will focus on this). Until our latest paper, scientists had only figured out how to do lattice surgery on “low-rate” codes (which we want to move past), or on high-rate codes but very inefficiently (using many ancillary qubits). In our new paper, we’ve developed an algorithmic method for performing safe lattice surgery on high-rate codes, efficiently. Our leadership in quantum error correction (QEC) would be impossible without our world-record commercial hardware fidelity. Quantum hardware that doesn’t have fidelity at our level will not be able to benefit from QEC in any meaningful way – until your hardware has good enough fidelity, QEC operations will only add noise. Our world-class fidelity, combined with our flexible QCCD architecture offering all-to-all connectivity, mid-circuit measurement, and feed-forward means that our team has an ideal playground for exploring the #QEC landscape, as we have proven over and over again.

Any sufficiently advanced technology is indistinguishable from magic. Famous words of Arthur C. Clarke. We are living in an era now where not only are these technologies advancing faster than ever but their real life application and eventual adoption is progressing at light speed. Imagine, what the application of quantum tech can do in the world of supply chain, where probability and predictability are so crucial. Whereas regular computers process information in 1's and 0's, quantum computers use quantum bits, or “qubits,” which can act as both 1 and 0. This lets each qubit perform multiple calculations simultaneously. The higher the number of qubits, the stronger the computation power. Technically, a quantum computer could perform calculations that a conventional computer cannot. Hence, the outcomes it can provide could also be vastly different and potentially superior. Just think about the applications to supply chain, transportation optimization, dynamic decision making on routing freight, disruption modeling, so many potential applications come to mind... #Technology #Quantumcomputing #supplychain #decisionmaking #optimization #Computers #qubits #predictivemodels

Quantum computers, unlike traditional ones, use #qubits that can represent more than just 0 or 1, making them incredibly powerful for solving complex problems. One such problem is the travelling salesman's problem, where a person needs to find the shortest route through multiple cities and return home. As the number of cities increases, traditional methods struggle with the sheer number of possible routes, but quantum computers offer a faster and more precise solution. By harnessing #mathematical methods and leveraging qubits, quantum computers can tackle combinatorial optimization problems like the travelling salesman's problem much more efficiently than classical computers. This breakthrough could revolutionize industries like logistics and resource optimization.

Quantum Computing: Revolutionizing Technology Quantum computing is an emerging field that promises to revolutionize information processing. Unlike classical computers using bits (0 or 1), quantum computers use quantum bits (qubits), which can exist in multiple states simultaneously due to superposition, allowing for vast data processing capabilities. Qubits: The Core Qubits leverage superposition, enabling them to be in a combination of states (both 0 and 1) at once. Two qubits can represent four states (00, 01, 10, 11), exponentially increasing computational power. Entanglement: Quantum Connectivity Entanglement interconnects qubits such that the state of one affects another, regardless of distance. This allows for complex, coordinated computations and faster data processing. Quantum Gates and Circuits Quantum gates manipulate qubits, forming the building blocks of quantum circuits. Common gates include Hadamard (creating superposition), Pauli-X (bit-flip), and CNOT (entangling qubits). Quantum circuits are sequences of these gates for complex calculations. Quantum Algorithms Quantum algorithms solve problems more efficiently than classical ones. Shor's algorithm factors large numbers exponentially faster, threatening current encryption systems. Grover's algorithm speeds up database searches quadratically. Decoherence and Error Correction Quantum decoherence, the loss of quantum information due to environmental interactions, is a major challenge. Quantum error correction codes, like the surface code, detect and correct errors without measuring qubits directly. Quantum Hardware Technologies for qubits include superconducting qubits (cooled to near absolute zero) and trapped ions (manipulated with lasers). Each has pros and cons in coherence, error rates, and scalability. Quantum Supremacy In 2019, Google's 53-qubit processor, Sycamore, achieved quantum supremacy by completing a task in 200 seconds that would take a classical supercomputer 10,000 years. Quantum computing will transform technology, solving complex problems beyond classical computers' reach. Ongoing research is advancing the field, promising new frontiers in science and industry. #QuantumComputing #Qubits #Entanglement #QuantumAlgorithms #QuantumHardware #QuantumSupremacy #Superposition #FutureTech #TechInnovation #Cryptography #DrugDiscovery #MaterialsScience #MachineLearning

President, IMPACT Institute for the Digital Economy - Technology Alchemist Innovating at the nexus AI/IoT/Blockchain Awarded Research Chair and Professor of Artificial Intelligence
Have you ever touched a quantum computer? Well... until I had the opportunity to see Dirac-3 at the QuantumTech Conference in DC https://lnkd.in/dsxcgvBk neither have I ! ... See details here: https://lnkd.in/dSfnqFY2 Milan Begliarbekov the Director of Quantum Foundry and main drive in the development of Dirac-3 innovative technology, gave an impressive presentation revealing the tech behind this amazing creation based on a fundamentally new quantum computing approach called Entropy Quantum Computing (EQC). It roots deeply in the intriguing principles of quantum mechanics. You see, one of the main problems that builders of quantum computers encounter is that in quantum information processing, loss and noise are usually detrimental and must be minimized. This is why quantum systems using atomic and alike qubits must be hosted in cryogenic vacuum chambers, and why photon loss is the roadblock to quantum communications and computing. In designing Dirac, rather than trying to create and manipulate pristine qubits isolated from the environment, Milan instead flipped the script around. Instead of trying to avoid loss and noise, he harnessd them to build quantum machines whose capacity and speed outmatch existing computing modalities. Driac-3 utilizes loss and decoherence, and turns entropy into super-power fuels of its computing engine. In sharp contrast to any existing quantum platforms, there is no need for cryogenic or isolated housing, and the implementation can use integrated photonics, leading to SWAP-C friendly devices, just like regular PC’s. Having a PC-like quantum computer at this point in time is beyond my wildest dreams!... But wait! this is not all! QCi (Quantum Computing Inc), which manufactures Dirac-3 have also developed a pocket quantum device that you can attach to your laptop as a powerful "quantum extension" that you can carry around to enable you to do anytime anywhere powerful AI computing. EmuCore https://lnkd.in/dShRMH35 is a photonic-inspired, FPGA based device which can be applied to solve a variety of problems related to serial data structures including time series prediction, image recognition, and text classification.
